My sleeve is stuck on

[Xpress]

So I decided to pull apart my 110 engine to try and repair the tranny problem I'm having (lack of 4th gear- well, it doesn't feel like it's going all the way into it).

I've gotten the entire head apart, except I can't pull the piston sleeve off. It's like it's been fused to the case..??? Any ideas? :wondering

sleeve or cylinder? for cylinder, throw a little heat at the bases and rap lightly with a soft mallet.

The sleeve and heatsink. It needs to be removed so that I can split the case and get at the gears.
